    This class is used by :ref:`"sox_io" backend<sox_io_backend>` and
    :ref:`"soundfile" backend with the new interface<soundfile_backend>`.

    :ivar int sample_rate: Sample rate
    :ivar int num_frames: The number of frames
    :ivar int num_channels: The number of channels
    :ivar int bits_per_sample: The number of bits per sample. This is 0 for lossy formats,
